Answer Posted / dheemanth kumar
Cyclomatic complexity is a software metric (measurement).
It was developed by Thomas McCabe and is used to measure
the complexity of a program. It directly measures the
number of linearly independent paths through a program's
source code.
M = E − N + 2P
where
M = cyclomatic complexity
E = the number of edges of the graph
N = the number of nodes of the graph
P = the number of connected components.
"M" is alternatively defined to be one larger than the
number of decision points (if/case-statements, while-
statements, etc) in a module (function, procedure, chart
node, etc.), or more generally a system.
Separate subroutines are treated as being independent,
disconnected components of the program's control flow graph.
[edit] Alternative definition
v(G) = e − n + p
G is a program's flowgraph
e is the number of edges (arcs) in the flowgraph
n is the number of nodes in the flowgraph
p is the number of connected components
[edit] Alternative way
There is another simple way to determine the cyclomatic
number. This is done by counting the number of closed loops
in the flow graph, and incrementing the number by one.
i.e.
M = Number of closed loops + 1
where
M = Cyclomatic number.
